Abstract-In this paper, the design and analysis of a compact size coplanar waveguide (CPW)-fed antenna for ultrawideband (UWB) applications is presented. The antenna has a compact size of 20 20 20 × × × 20 20 20 × × × 1.5 1.5 1.5 mm and provides a good impedance matching over the entire bandwidth of 3.2-14.3 GHz. The characteristics parameters, i.e. return loss, VSWR and radiation pattern, are analyzed using HFSS 11.0 software.

“…Various CPW-fed antennas have been reported in literature such as multiband [3][4][5][6][7][8], CPW antennas with added strip for WLAN [9][10][11], and asymmetric coplanar strip antennas [12][13][14][15][16][17][18][19][20]. However, majority of these designs have large antenna dimensions and do not cover all the major bands of WLAN/WiMAX/LTE [13][14][15][16]18].…”

“…In order to reduce size and avoid the complexity, major overlapped slots have been introduced in the proposed antenna design along with two strips above and below the main radiating patch. Compact ground plane length ratio to the overall length of the antenna is optimized to achieve 50 Ohm impedance matching by adjusting the microstrip width and gap between the microstrip and the sides of the ground plane [6,8,24]. In Table 1, a comparison is made between different existing CPW designs found in literature and our proposed work.…”

This paper presents a dual-band coplanar waveguide (CPW) fed printed antenna with rectangular shape design blocks having ultrawideband characteristics, proposed and implemented on an FR4 substrate. The size of the proposed antenna is just 25 mm × 35 mm. A novel rounded corners technique is used to enhance not only the impedance bandwidth but also the gain of the antenna. The proposed antenna design covers two ultrawide bands which include 1.1-2.7 GHz and 3.15-3.65 GHz, thus covering 2.4 GHz Bluetooth/Wi-Fi band and most of the bands of 3G, 4G, and a future expected 5G band, that is, 3.4-3.6 GHz. Being a very lowprofile antenna makes it very suitable for the future 5G Internet of Things (IoT) portable applications. A step-by-step design process is carried out to obtain an optimized design for good impedance matching in the two bands. The current densities and the reflection coefficients at different stages of the design process are plotted and discussed to get a good insight into the final proposed antenna design. This antenna exhibits stable radiation patterns on both planes, having low cross polarization and low back lobes with a maximum gain of 8.9 dB. The measurements are found to be in good accordance with the simulated results.

“…Creating a wide slot on the ground is another method to enhance impedance bandwidth of the antenna. Recently, many wide slot antennas have been reported for broadband applications such as rectangular slot [7,8], triangular slot [9], rotated slot [10] and pentagonal slot [11]. The addition of tuning element with a proper dimension and location is another approach to improve the performance of a wide slot antenna.…”

Abstract-A wide slot antenna with Y shape tuning element is presented for wireless applications (GSM 1800, WiMAX, PCS and ITM-2000). The proposed antenna is fabricated on an FR-4 substrate (tan(δ) = 0.02, ε r = 4.3) with the thickness of 1.6 mm. On the top layer of the substrate, a 50 ohm microstrip line is fabricated which is terminated in Y shape tuning element. On ground plane, an irregular wide slot and triangular notch are etched. In addition, for performance improvement two triangular shaped parasitic slots are embedded on the ground plane. The proposed antenna is energized by the microstrip line. It exhibited the bandwidth of 127.55% from 1.15 GHz to 5.2 GHz for |S 11 | < −10 dB. Surface current distribution and radiation pattern at resonating frequencies 1.25, 1.9 and 4.2 GHz are analyzed. Impact of parameters on S 11 characteristic is also studied to know the behavior of the antenna.
